There are
two
behaviors associated
with this
feature
that
help
to
preserve
the integrity of the
hard
disk’s
password:
•
The administrative
password
will
only work
to
unlock a hard disk on
the
computer on which
the hard
disk password was created. This means a
password-protected hard disk can
not
be removed
from one
computer, placed
in
a second computer and be unlocked using
the
administrative
password on
the
second
computer.
•
I
nstalling
an administrative
password on a computer after the hard disk password has been created
will
not
enable unlocking
of the
hard disk using
the
administrative
password.
Trusted Platform Module
(TPM)
NOTE:
Computers shipping into China are not equipped with the TPM
feature.
NOTE:
The TPM feature supports encryption only
if
the operating system supports TPM. For more information, see
the
TPM software documentation and the help files that came with the
software.
TPM
is a hardware-based security feature
that
can be used
to
create and manage
computer
-generated
encryption
keys.
When
combined
with
security software,
the TPM
enhances existing network
and
computer security by enabling features such
as
file
protection capabilities and protected e-mail.
The
TPM
feature is enabled through a system setup
option.
NOTICE:
To
secure your TPM data and encryption keys,
follow the backup procedures documented in the Archive
and
Restore section of the EMBASSY Security Center help file. In the event of these backups being incomplete,
lost,
or
damaged, Dell
will
be unable to assist in the recovery of encrypted
data.
